I have a http://www.precisionairsoft.net/G-P-...R-p/gpr021.htm
If I put in a tightbore barrel will this increase accuracy, distance or FPS??
What would be the best barrel, Prometheus, Systema, etc?
Last question, if this shoots at 360 FPS with .20g bb's what would the FPS be with .25g bb's?
Thanks.
